If the typical balance on Lucy's credit card is $650 and the interest rate (APR) on her credit card is 18%, how much in interest

Mariana [72]

$9.75

<h3>Further explanation </h3>

Given:

The typical balance on Lucy's credit card is $650.
The interest rate (APR) on her credit card is 18%.

Question:

How much in interest would you expect Lucy to be charged in a typical month?

The Process:

This problem includes the type of determining simple interest.

$\boxed{ \ I = P \times r \times t \ }$

where,

I = simple interest
P = principal (initial amount)
r = annual interest rate
t = time (in years)

This time we will find out how much in interest we would expect to be charged in a typical month.

The data is as follows:

P = 650
r = 18% or $\frac{18}{100}$ or 0.18
t = $\frac{1}{12}$ year (one month)

Let us calculate how much in interest we would expect to be charged in a typical month.

$\boxed{ \ = 650 \times \frac{18}{100} \times \frac{1}{12} \ }$

$\boxed{ \ = 65 \times \frac{3}{10} \times \frac{1}{2} \ }$

$\boxed{ \ = \frac{195}{10} \times \frac{1}{2} \ }$

$\boxed{ \ = \frac{97.5}{10} \ }$

$\boxed{ \ = \frac{975}{100} \ }$

Thus the amount of interest we would expect Lucy to be charged in a typical month is $ 9.75.

We must be able to distinguish between simple and compound interest. Please learn about this in the link attached below.

A large storage tank, open to the atmosphere at the top and filled with water, develops a small hole in its side at a point 10.4

vlabodo [156]

Answer:

Therefore the diameter of the hole is $1.94 \times 10^{-3}$ m.

Step-by-step explanation:

Bernoulli's equation,

$P_1+\frac12 \rho v^2_1+\rho g h_1= P_2+\frac12 \rho v^2_2+\rho g h_2$

P₁ = P₂= atmospheric presser

$\rho$ = density

$\frac12 \rho v^2_1+\rho g h_1= \frac12 \rho v^2_2+\rho g h_2$ [since P₁ = P₂]

$\Rightarrow\rho (\frac12 v^2_1+ g h_1)= \rho(\frac12 v^2_2+ g h_2)$

$\Rightarrow\frac12 v^2_1+ g h_1= \frac12 v^2_2+ g h_2$

$\Rightarrow\frac12 v^2_2-\frac12 v^2_1=g h_1- g h_2$

$\Rightarrow v^2_2- v^2_1=2g h$ [ $h_1-h_2=h$ ]

Here $v_1\approx 0$

$\Rightarrow v^2_2=2g h$

$\therefore v_2=\sqrt {2gh$

Here g= 9.8 m/s² , h = 10.4 m

The velocity of water that leaves from the hole $v_2$ = $\sqrt {2\times 9.8\times 10.4}$ m/s

=14.28 m/s.

Given, the rate of flow from the leak is $2.53\times 10^{-3}$ $m^3/min$

$=\frac{2.53\times 10^{-3}}{60}$ $m^3/s$

Let the diameter of the hole be d.

Then the cross section area of the hole is $=\pi (\frac d2)^2$

We know that,

The rate of flow = Cross section area × speed

$\Rightarrow \frac{2.53\times 10^{-3}}{60} =\pi (\frac d2)^2\times 14.28$

$\Rightarrow (\frac d2)^2=\frac{2.53\times 10^{-3}}{60\times 14.28\times \pi}$

$\Rightarrow d= 1.94 \times 10^{-3}$

Therefore the diameter of the hole is $1.94 \times 10^{-3}$ m.
